Is there a general rule for speaker positioning against a wall? Looking to upgrade from my Radius range starting with the front 2, I'm listening to more music these days through my Sonos system and am really missing good 2 channel stereo sound, I would say the split these days are 50/50 movies/music. My room size is 4.5m by 3.5m and will also be upgrading my amp to an Arcam AVR280 or 350. Looking at floorstanders as standmounts are a bad idea with the kids running about, scared that they will knock them off. Was thinking of the BR5's, RS5's or the RS6's, but what's the general census of these speakers in a room that size? And what space would they need to breathe to get the best out them? Thanks, Bro.
